SPECIFICATION forming part of Letters Patent No. 480,427, dated August9, 1892.

Application filed October Z0, 1891.

To all whom it may concern:

Be it known that I, JOHN G. GRAY, a citizen of the United States,residing at Connersville, in the county of Fayette and State of Indiana,have invented certain new and useful Improvements in l/VaterproofBurial-Cases; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

My invention relates to that class of cases or receptacles used toinclose deceased persons or the coihns and caskets containing the same.

My invention consists in a case or receptacle of suitable proportions toreceive the deceased person or the coffin or casket containing the same,which is provided with a cap or cover made air-tight and adapted to shutdown over the case o1l receptacle closely, forming an air-chamber of thearea inclosed inthe interior of the cover and the case, the air in whichis compressed by the water rising in the space between the cover and thecase until the atmospheric resistance in the air-chamber checks therising of the water in the space.

In the drawings, Figure l. represents the case with the air-tight cap orcover in position. Fig. 2 is a vertical cross-section of the same.

In Fig. l, A represents the air-tight cap or cover, and B the case orreceptacle in which the deceased person or the coin or casket containingthe same is placed.

In Fig. 2 like letters represent like parts, while C represents thespace between the case or receptacle B and the air-tight cap or cover A.

D shows the rim or flange which projects Serial No. 409.292. (No model.)

out from the upper portion of the exterior of the case or receptacle B,and E represents the spring-lock as it is made fast to thenterior of thecap or cover A and catches beneath the rim or ange D. Said spring-locksmay be removable and adjustable for convenience in shipment. As theWater rises around the structure the escape of the air from the interiorof the case is cut off and the water can only ascend to that point wherethe resistance of the compressed air will meet and counteract itsfarther upward progress. The cap or cover being constructed air-tight,the atmospheric resistance is continuous and permanent and a waterproofburial receptacle is produced.

The tendency of the opposing forces to raise the cap or cover from itsposition by an increased volume or depth of water is obviated by thespring-locks E, which hold the said cover to the case B and prevent itsdisplacement.

The case or receptacle is so constructed as to be air-tight andimpervious to water, and when provided with the air-tight cap or coverarranged as already described it will be seen that a waterproofburial-case is the result.

Having thus fully described my said improvement, what I claim as new,and desire to secure by Letters Patent, is-

In a waterproof burial-case, the air-tight cover A, the case B, madeimpervious to water, arranged to leave an air-space C between theirvertical sides, the flange D, and the spring locking-lever E,constructed and operating substantially in the manner and for thepurpose as set forth and described.

In testimony whereof I affix my signature in presence of two witnesses.
